Hi there!
Usually some users posts topics with Google Translator (or your favourite insta-translator) and people unfollow the threat fast. Same happens with webs or new advertisements: if you can't understand what are they talking about in some aspects the decision is obvious: don't follow the project. The worst thing is what happens when you translate a text and you can't do replies because lenguage is a trouble.
I offer a complete service of translating texts in perfect spanish (I'm native and spanish phylologist) and, if you want, community management of Facebook & Twitter (in english and/or spanish) and the most important factor for your interest: I can promote the topic and send feedback to users who wants to know a little bit more.
Spanish community in bitcointalk is growing and they can be interested in what you want to say. Think on it.
If you are interested in my services (or you got any offers for somebody like me) only MP me and I'll make an offer depending of what is the work to do
